How to Install Window Blinds

Installing Blinds

Hanging your custom window treatments can be a stress-free adventure if you take a few minutes to plan. Gather all of your equipment and sit down to read the instructions. Make sure to familiarize yourself with each step of the process before you begin. Taking time now can save you time later.

Whether you're installing custom blinds or off-the-shelf window treatments, vertical blinds or vinyl mini-blinds, check the packing list to make sure you have the correct materials and accompanying hardware for your particular blinds. You may need to purchase wall anchors or toggle bolts if you're attaching brackets to a surface other than wood.

Blinds Installation Tools

Items you will need:
  • Tape measure
  • Level
  • Drill and bits
  • Screwdriver
  • Pencil

Blinds Installation Steps

The following steps are general guidelines for putting up most blinds. Your blinds will come with installation instructions - read and follow these carefully. The manufacturer's directions take precedence over any conflicting instructions listed below.

1. Determine bracket placement.

For all mounts, keep the headrail level, even if the window is not. For an outside mount, center the headrail and draw a small line 1/8" beyond the ends and just below. For a ceiling mount, center the headrail over the window and make a pencil mark 1/8" beyond the ends. For an inside mount, mark below the headrail on each end.

Hold each bracket in place to indicate the locations for the pilot screw holes. Use a level to ensure that the holes will be even with each other. Make adjustments if necessary. If adding a center bracket, make sure its location will not interfere with operation.

2. Attach the brackets.

If you're mounting the brackets on a wood surface, drill pilot holes slightly smaller than the screw. Insert the screws that came with your blind. You can use a little soap on the screw thread to help it go into the wood easier. For surfaces other than wood trim or framing, follow the manufacturer's directions for wall anchors or toggle bolts.

3. Install the headrail.

Place the headrail securely into the brackets per the manufacturer's directions. Close the bracket gate until it snaps into place. This step ensures that the headrail will remain safely in the bracket.

4. Attach the valance and vanes.

Attach the decorative valance per the manufacturer's directions. For horizontal blinds, attach the wand for adjusting the vanes. For vertical blinds, attach the hardware for adjusting the vanes, and then attach the vanes into clips in the headrail.

Blinds Installation Safety Tips

Always use eye protection when drilling.

Even if you don't have children around the house, it's still a good idea to be prepared for young guests. Dangling cords present a choking hazard. Simply shorten the cords to get them out of reach for young children. Slide the knob higher up the cord, retie the knot that secures the knob, and cut off the excess. Another way to prevent children from becoming entangled in cords is to install cord cleats. You can even use a clothespin or small clamp to keep the cords out of reach.

If you've installed blinds on a patio door or near any other pathway, the lift cord may dangle near the floor. To prevent tripping on it, move it away from the door opening and secure it with a clothespin or small clamp.

Installation Is Complete! Now Enjoy the View

Once you've installed your window treatments, keeping them beautiful is easy. Most blinds require periodic dusting and occasional cleaning with mild soap and water. Avoid chemical cleaners. To enjoy your blinds for years, follow the cleaning instructions that came with your blinds.
